OIL-CUP.

Specification of Letters Patent.

Patented Feb. 1, 1921.

Application filed ctober 9, 1919. Serial No. 329,426.

To all whom t may cour-cra f Be it known that l, lllrnrmar l-l. Haar, a citizen oli the United States, residing` at Green Bay, in the county of Brown and State of lllisconsin, have invented. certain new and useful improvements in (lil-Cups; and l do declare the following to be a i'ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i v

This invention relates to improvements in oil cups, more particularly to that type ordinarily used on cross heads and other parts of locomotives.

The principal object is to provide a simple and practical oil cup especially constructed y.

for use on machinery in which the vibration is suiiicient to render the ordinarily constructed oil cups practically useless.

Another object is to provide anoil cup in which the cover is so'constructed and mounted on the receptacle, that it will invariably automatically seat itself properly.

A further object is to construct and mount a cover for an oil cup in such a manner that it may be used for adjusting' the oil Vdow controlling valve.

With the above and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement ci. yparts fully described and claimed.

l attain these objectsiby constructiup` the cups as illustrated in the accompanying drawings, in which- I .li`i, ure l, is a vertical` sectional view of the improved oil cup;

Fig. 2, is a sectional view taken on the line 2-2 or Fig. l, and- F 3, a sectional view taken on the line 3-3 of Fig. l.

Similar numerals oi reference designate similar parts throughout the several views.

Reference is now had to the drawings in which the receptacle l is shown as being oi' the ordinary construction and having a depending, threaded nipple 2 for threaded en gagement in an oil hole in a cross head or other part of a machine. rlhe receptacle 1s provided with a cover 3 of any preferred form, it being; shown in the drawings substantially semi-elliptical in cross-section, although it may well be or' a diilerent shape.

4While any suitable valve may be used for .bore 6 oi the as will be more regulating the llow oi oil from the receptacle througl'l the outlet of the nipple 2, I preferably construct a needle valve casing or hollow elongated body el provided at its lower end with a diametrically reduced threaded nipple o which 1's screwed into a centrally disposed threaded socket in the bottom of the receptacle, said body having a bore of a uniform diameter from its upper end to a point substantially midway the length of the body d at said point the bore 6 is slightly reduced to receive the small lower end T of the needle valve or screw valve 8. -ita point adjacent the juncture ol the body l and threaded nipple 5, the di ameter or the bore is decreased to forni a beveled seat 9, for the tapered lower end T of the needle valve.

For the purpose oit' admitting oil to the .Q 4.1

body elftwo pairs or diametrically oppcsitely positioned openings Gil are provided, as shown in full lines in Fig. 3 and dotted in Figs. l and 2, this being the preferred, though not absolutely essential manner of accomplishing,v the desired result.

lhe needle valve is preferably, though not necessarily, oi greater diameter at its upper end than at its lower end, said upper end being,` threaded to engage threads in the large upper end et the bore. y it a point above the upper end of the body el, the diameter of the needle value 8 is increased to form an annular shoulder 9 on 'the lower face olf a head l() which is provided on the ext-reine upper end with .terally direc ed angular ears ll., said ears beingv adapted for reception in a similarly shaped recess l2 in the lower `iaceoi' the. cover 3, so that the needle valve mayV be' manually adjusted 'through rotation oi saidficover. The above described connection between the cover and valve is the preferred form but it is understood that any other suitable means may be employed with good results.

The cover 8 is preferably formed with studs or bosses 13 whose adjacent walls form the recess l2, said bosses having, Vfiat lower faces, upon which a pair ot substantially l..- shaped brackets 14- are riveted or otherwise fastener. Slidable vertically on the valve body e is a plate l5, .preferably stamped from a single piece of metal. An opening is formed in said plate to receive the valve body d, and the metal forming the wall of the opening` is bent at right anales to the the other plate proper to form a guide llange 1G, which serves to prevent canti ot' said plate. A pair ot laterally oppositcly directed substantially L-shaped arms are formed on said plate, said arms and the aforementioned brackets 'lll being' connected by suitable linl; 17.

butting against the shoulder 9 ol the head l0 isla plate or dist; lll, which preterably has a depending` flange on its periphery, said plate coactinp; with the lower plate l5 to compress a coil springi 19, which preferably surrounds the valve body 4r. and through its expansive action retains the cover in closed position. lt is understood that although the enlarged head and tie upper plate 18 are the preferred elements to act against the spring, l mayveinploy any other suitable means.

For the purpose oit assisting the coil spring in preventing accidental adjustment of the valve, l have provided a substantially inverted U-shaped spring` 20, which is mounted in a transverse opening` in the head ot the valve and has a portion o' the arms trictionally engaging` the receptacle or cup wall. This spring prevents vibration (of the guide rod or cross head upon which the cup uis mounted) trom causing' the valve to rotate and close the outlet.

Because of the trictional engagement between the elements 9 and i8, between the elements l5 and i9, and between. the screwthreads el elements l and 8, caused by pressure et the spring` i9, the latter may properly be termed yielding means tor resisting accidental adjustment of the needlevalve or adjustable feed regulator 8. Simi.- larly. the spring` 20 may properly be termed yielding means for resisting accidental adjustment of the needle-valve. lt is obvious that these means coact for controlling the needle-valve and that this valve controls the springs 19 and 2O by securingthem in their operative positions. Either oi the springs i9 and 20 will control. the needle-valve 8 ir` springl becomes breiten, but greater e'hiciency is obtained by their combined action.

lhen it is necessary to refill the cup with oil the cover is raised tree from the head of the valve and is tilted or slid to one side of the cup whereupon oil may be readily poured into said cup. VThe needle valve may be adjusted by employing` either of two different methods. rlhe first being,` to replace the cover, the head oli the needle-valve automatically seating,` itsellz in the recess in in the lower tace of the cover. The cover may now be turned and with it will turn the needle-valve whereby the l'low ot oil is controlled.

The second method of adjusting the needle-valve is to turn it with the fingers before the cover is replaced and when the cover in closed position it will lock the needle-valve against accidental movement.

From the foregoing description, taken in connection with the accompanying drawings, the construction and opera-tion of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and minor details o'l construction may be resorted to without departing` from the principle or sacrificing any ol the advantages oli the claimed invention.

l claim:
